National gasotine lead use is not a valid index of exposure at NHANES HI sites Over 50% of the apparent blood lead decrease is attributable to demographics v 5 to 10% of the apparent blood lead decrease is attributable to gasoline lead exposure The blood lead decrease of 0.3 to 0.6/ig/dl attributabte to gasoline lead is consistent with the observed air lead decrease A significant blood lead time trend remains after accounting for demographics and gasoline lead exposure TEH 0532601 i DUP050033869 Gasofine Lead and NHANCSH Wood Lead Levels TEH 0532602 DUP050033870 mr-*nrr$ None OEM DEM.

This consists of a complete eleotrolytlc white lead plant which uses a portion of ths lead refined at the Lead Rs finery as a raw material far the electrolytic corrosion of lead to produoa whits lead.

S. was absorbing, storing and excreting sufficient lead to substantiate the diagnosis of chronic lead intoxication.

Other Lead Uses Except for the lead covered letters on the main sign at the entrance to the Pavilion, other uses of lead are traditional.

Through previous first issue of Lead described experience with lead-asbestos how a combination lead-asbes mats.

'- ite Lead and our regular grades of Red Lead and Litharge must come from National Lead or Fuller in line with these agree ments .

Y* on L0/I3/S5* The National Lead Fence were inspected first* 1) Single Pigment Paints a) Oil base paints were shown of Lead Carbonate* Lead Sulfate, Zinc Oxide* Asbestine, Anatase Titanium and Zinc Sulfide-, b) All applied three coats over cedar and exposed yearly since June 26* 1950# c) These show wood holding properties and mildewing* d) The white lead carbonate panels look best for wood holding.
